BUTTON-FASTEN ER.

SPECIFIGATION forming part of Letters Patent No. 572,846, dated December 8,1896.

Application fi1ed April 27,1895. Seria1No. 547,389. (No model.) Patented in Germany February 18, 1894:, No. 78,464.

Be 'IJ known that I, IIERMANN FRIEDRIC-I-I WELKE, 21 subject of the King of Prnssia, German Emperor, residing at Hagen, \Vestphalia, in the Kingdo1n of Prussia, Germany, have invented oertain new and nsefn1 I1nprovements in Button-Fasteners, (for whioh Letters Patent were gmnted to me in Germany, No. 78,404, dated February 18, 1894;) and I do hereby deolare the following 110 be a full, e1ear, and exact desoription of the invention, snob as wil1 enab1e others skilled in the art to whieh it appertains to make and nse the sanie.

My inveniion relates 'uo that o1ass of button-fasteners provided with spring-aotnated jaws, one o ho1d the button and the ouher the pin, and whioh are caused to move toward eaoh other to foroe the pin through the Ina terial and form 2L loop therein through the shank of the button.

The invention oonsists, first, in a novel oonstruotion of recess for reoeivng the button, in eo1nbinaton with a spring to rest npon thehead of the button and a spring-actuaued lever-arm aot-ing in conneetion with the spring whereby the button is firrnly held in proper position re1ative to the pin.

IIJ further oonsists in so eonnecting the 1e ver-arm and its aotnating-spring with the device that said spring shell not to normally 1101d the jaws open f0r aotion.

It fnrther eonsists in the oombinafuion, with the sprin g-plate for holding the pin,of a hookarn1 pivotally eonneoted with one of the ar1ns with its hook end 130 move in 2, slot or groove under the spring-plate, whereby the s2nne shell aot to hold the spring away from the faoe of the jaw when the jews are open 110 permi1; t11e ready insertion of the pin and 1:0 be withdrawn fro1n ae'oion with the springp1ate as the jaws are olosed t0 eause the p1ate 130 tightly grip t]1e pin-head.

It further oonsists in oertain nove1 featnres in the oonstrnotion and arrange1nents of par'os, a11 as hereinafter described.

In the aeoompanying drawings, Figure 1 is a side elevation of the jaws with a part of ;he handles broken away, taken from the side to show the kook-arm with the jaws in their open position. Fig. 2 is a similar view showing the jaws o1osed with the end of the jaws in seotion. Fig. 3 is a similar view to Fig. 1, taken from the opposite sicle. Fig. 4 is a plan view of the spring-plate 'or holding the pin. Fig. 5 is a view of the springpate for holding the button; Fig. 6, a perspective view of the pin; Fig. 7, a perspeotive view of the kook-arm; Fig. 8, a view showing the button applied to the materiai. Fig.. 9 is a perspeouive view of the standard.

The jaws A A and handles B B may be of any nsnal or preferred eonfignration, exoept in the partieulars hereinafter referred to.

The forward end of the jaw A, whioh reoeives the button, consists of a donble-siaepped portion a 0,, with the forward faee beveling or inclining inward with the reoess or socket b, wheh gnides and for1ns the pin into 100pfor1n, looated in rear of The faoe or sfsepped portion a.

Conneoted to the forward faoe of the jaw A is a spring-plate d, whioh overhangs the stepped portion a and orms, in oonneotion with the face of the stepped portion, a oavity for reoeiving the head of the button.

Pimtally oonneeted to the side of the jaw A is a lever-arm 0, With its forward end bent at an angle to overhang the face of the spring plate d. The rear end of 'ohis lever-arm has conneoted to it a spiral spring D, whioh in turn is oonneoted in rear of the pivoua1 con neouion of the jaws with the handle B of the jaw A and said parts aotng in snoh manner that as the jaws are olosed the spring wi11 ao1: on the lever-arm and oause the 00e C of the ang1e-arm of the lever 'uo engage the springp1ate cl and net in conneotion therewith to firrn1y ho1d fl1e bn tton fast during the process of forcing the pin throngh the shank of the button and compressing or forming the same into shape, thns avoiding assis'nance from the hand of Lhe operator to 1101d the button. The spring D a1so acts to draw the jaws open after the operation is eompleted ready for reaotion.

The upper faoe of the jaw A is made flat and is provided neer i ts forward end with 21 noteh or reoess E, made in 0011 o2we form, hereinafter referred 130. Conneoted to this faee is a flat spring-plate E, which p1a1e neer ins forward end is provided With a noteh or reoess e, opening outward to the side of the jouw, the notoh being of snoh depth that when the pin recess 01 socket b.

is placed therein the point shall be directly inline with the center of the shank of the button or in proper position relative to the By this arrangement of the slot it will be seen that the pin will be held firm1y in direction longitudinally of the jaw, which, as will be readily seen, Wil1 a1ways insure the proper entrance of the pin into the socket and around and through the loop of the button, as a11 tendency (0 move the pin in this action is longitudinally relative to the jaws. A hook-arm G is pivotally connected with the arm A With its hook er bent end to enter the notch 01 recess E, Which notch, as before stated, is made in coneave form, and the 1ength of the hoek-arm and its pivotal connection With the arm A is such that when the jaws are fully open te commence operati0n the hook-arm Will be forced forward and up the inclined face of the recess and act t0 raise 0r e1evate the spring-plate te f0rce said spring away from the jaw and when closed t0 draw it away from such action and permit the spring to exert it-s entire force. By this constrnction and arrangement it will be seen that the pin can be readily put in p1ace and that as soon as the action is commenced the spring Wil1 immediately act and firmly grip the head of the pin. This arrangement a1so facilitates the remova1 of the goeds from the jaws after the button has been applied, as when the jaws are opened after app1ying the button the hook-arm G again engages the spring and forces it away from the jaw.

The device may be connected to a standard II by an adjustable pivotal connection H, which may in turn be mounted in a base II which may be connected te the work-bench, the arrangement of parts permitting the device to be adjusted vertically to change its height relative to the tab1e or its oscillation re1ative to the base.

Having n0w described my invention, what I claim as new, and desire t0 secure by Letters Patent, is

1. In a device for connecting buttons 0 articles, the combination With the jaw for holding the button, a recess to receive the button, a concavity formed in said jaw te form or guide the pin, a spring t0 rest upon the head of the button and a spring-actuated lever-arm acting in connectionwith the spring substantially as and for the purpose set forth.

2. In a device for connecting buttons te articles, a spring t0 engage the head of the button, a lever-arm having a forward extension te engage the spring, a spring connected te said lever-arm and to the operating-handles, and acting snbstantially as and for the purpose set forth.

3. In a device 'or connecting buttons te articles, the pin-holding jaw, a recess formed therein having a ccncave face, a spring-plate te held the pin arranged over said recess, an arm to play in said recess, and connected With the opposite jaw, substantially as described whereby t0 automatically contro1 the tension of the spring as set forth.

In testimony whereof I have aflixed 1ny si gnature in presence of two witnesses.
